Assembled reels selected as specified in 4.5.2 shall be loaded with hose and operated by hand to test all functions,
32、fits, clearances and adjustment (see 3.15). The holding brake operation shall applied sucessfully not less than three applications. 4.7.2 Pressure tests. 4.7.2.1 Hvdrostatic test. Prior to installation of hose, each reel shall be hydrostatically proof-tested to 400 psi. The pressure shall be held fo
33、r 5 minutes during which time there shall be no leakage or other signs of weakness (see 3.3.1). 4.7.2.2 Collapse pressure test. Each reel shall have hose or hoses, identical to the hose to be used in service (see 3.2.2), attached and wound on the reel. The reels and hose shall be pressurized with wa
34、ter to 240 psi. The pressure shall be held for 5 minutes. The pressure shall then be reduced to O psi and the hose shall be unwound from the reel. The drum shall show no evidence of collapse due to the growth or shrinkage of hose under pressure. Other reel parts shall show no evidence of damage or d
35、istortion due to this test. 4.7.3 Operating test, reel Dressurized. Upon completion of the collapse test (see 4.7.2.2), the reel and hose shall be repressurized as specified in 4.7.2.2 to 175 psi and the hose shall be reeled on and off the reel while under pressure. The reel shall operate smo;tbly w

The type II reel shall be subjected to the spraytight enclosure test in accordance with MIL-STD-108. 4.7.5 Shock test. The high impact (H.1.) shock tests shall be grade A, class I, type A in accordance with MIL-S-901. T
37、he reel shall be completely assembled (including hose), and shall be mounted on the shock machine in a manner simulating a typical shipboard bulkhead installation. The number of blows shall be as specified in MIL-S-901. Hose used for the H.I. shock test of reels need only be the same size, weight an
